This may be only tangentially related to your specific question, but in the past in the United States, physicians sometimes would make decisions that contradicted the parents' wishes. In my mother's case (born in New York in 1925), her parents wanted the name Doris, but (according to my mother), the physician liked my grandmother's name, Lillian. So, he put Lillian down on the birth certificate. When my grandmother went to register the birth several days later, she (apparently) had the name changed to Doris. But Lillian remained on the official birth certificate for the rest of my mother's life. She decided to go by "Doris Lillian."
